I’ve designed and built data platforms end-to-end: data instrumentation and ingestion, data processing, analytics, data lakes and warehouses, OLAP databases, data products, you name it.

Lots of experience with Apache Kafka and Apache Flink and a solid understanding of most of the other popular streaming platforms and frameworks.
